摘要：Tribolium castaneum is one of the most destructive insects infesting cereals and their products worldwide. The quality changes of wheat flour infested by initial 0 (as a control), 2, 4, 6, and 8 adults of T. castaneum in 500 g wheat flour were investigated at 15, 25, and 30°C after different storage periods. The quality of wheat flour changed little during 150 d storage at 15°C, but it significantly decreased with increasing initial insect density and storage time during 150 d storage at 25 and 30°C. The moisture content, fatty acid value, falling number, and protein content of wheat flour were 12.21±0.19%, 190.08±3.51 mg KOH (100 g)-1, 208.67±7.23 s, and 14.25±0.02% after 30 d storage at 30°C, respectively. The wet gluten content and dry gluten content of wheat flour could not be detected after 90 d storage at 25 and 30°C. These results provide useful information for maintaining wheat flour quality.
